To easily extract a winding body wound on a core from the core.
In a manufacturing device of the winding body 50A formed by winding a belt-like body 50 by the core 1, the core 1 includes a pair of shaft-like bodies 2A and 2B having an inner peripheral surface part opposed by sandwiching a clearance S for inserting one end side of the belt-like body 50 and an outer peripheral surface of winding the belt-like body 50 on the outside of this inner peripheral surface part and divided over the axial direction, and a rotation switching mechanism 5 for rotatably supporting at least one shaft-like body 2A among the pair of shaft-like bodies 2A and 2B and switching a rotational position of the pair of shaft-like bodies 2A and 2B between a first rotation position for forming the clearance S between the opposed inner peripheral surface parts of the pair of shaft-like bodies 2A and 2B and a second rotational position for sandwiching one end side of the belt-like body 50 inserted into the clearance S by inclining the opposed inner peripheral surface parts of the pair of shaft-like bodies 2A and 2B to one side in the rotational direction.
